My flat is located in the fifth district, a relatively calm area. There go direct busses to the direction of the inner city, you will also reach the U4 metro line quickly.
The flat is a single room studio apartment with a bathroom (w/ bathtub). The room is very bright and there is everything you would need as I live there myself outside of summer time. The windows face the patio, so you won't hear the main road nearby.
There is an electrical piano you can play on.
